Calculate the temperature of the Pacific Ocean and calculate the temperature differences of this throughout the year e.g. the maximum and minimum temperatures.

Pacific Ocean Temperature Differences
Minimum temperature: 27°F (-2.8°C)

Maximum temperature: 91°F (32.7°C)

Temperature Variations Throughout the Year
In tropical regions temperatures remain warm year-round, averaging 79–84°F (26–29°C).

In temperate regions winter temperatures can drop to 50–55°F (10–13°C), while summer temperatures rise to 60–65°F (16–18°C).

The River Nile is 4132 miles long – round to the nearest 1000, 100 and 10.

Ans) Nearest 1000: 4000
Nearest 100: 4100
Nearest 10: 4130

Where are the coldest waters in the world?

Ans) The coldest water is the Ross sea located in the Coastal because the average temperature is -1.9°C.

Silver

Research the temperature of the Pacific Ocean and calculate the temperature differences of this throughout the year e.g. the maximum and minimum temperatures.

Ans) The minimum recorded temperature is around 27°F (-2.7°C)
The maximum temperature can reach 91°F (32.7°C)
The largest temperature differences occur between the polar regions and tropical areas ,
with seasonal shifts affecting different parts of the ocean at different times.

Locate the 3 deepest oceans and calculate the combined depth of these in metres and km.

Ans) The Pacific Ocean has an average depth of 4,280 meters and 4.28 km
The Atlantic Ocean has an average depth of 3,646 meters and 3.646 km
The Indian Ocean has an average depth of 3,741 meters and 3.741 km
The 3 oceans combined depth is:
In Metres = 11667m
In Kilometres = 11.667km

Then order these oceans by the depth and then by temperature too.

Ans) In order the oceans by depth are :
1. The Pacific Ocean
2. The Atlantic Ocean
3. The Indian Ocean

In order the oceans by temperature are :
1. The Indian Ocean = ~22°C (72°F)
2. The Pacific Ocean = ~19°C (66°F)
3. The Atlantic Ocean = ~17°C (63°F)

Gold

The Atlantic Ocean covers approximately 106,400,000 square kilometres which is 20% of the Earth’s surface. How many square kilometres is the Earth’s surface?

Ans) Earth’s surface area is approximately 532 million square kilometres.

How many square kilometres is the surface of the earth covered by land? What percentage is this?

Ans) The land covers about 154.3 million km², which is 29% of Earth’s surface.

Can you order the oceans by square kilometres too?

Ans) The order of oceans from largest to smallest is like this:
Pacific > Atlantic > Indian > Southern > Arctic.🌎
